Paraffin Wax
Stable and Reliable Properties: Paraffin has stable physicochemical characteristics and a well-defined molecular structure, ensuring consistent performance across a wide range of applications.
Colorless, Odorless, and Tasteless: Its neutral appearance and lack of smell or taste make paraffin especially suitable for medical, food-related packaging, and cosmetic uses.
Cost-Effective and Widely Available: Derived from petroleum distillates, paraffin is inexpensive and readily available, supporting large-scale industrial and commercial applications.
Excellent Thermal Performance: With a large latent heat of phase transition, paraffin is effective for thermal storage, insulation, and temperature-regulating applications in construction and industry.
Paraffin is a hydrocarbon blend obtained from specific petroleum distillates, shale oil, or other bituminous mineral oils. It is mainly composed of solid alkanes and is colorless, odorless, and tasteless, typically appearing as a white to light yellow translucent solid. Chemically, paraffin consists of straight-chain saturated alkanes with different molecular weights, following the general formula CₙH₂ₙ₊₂. According to its physical form, paraffin is commonly divided into liquid paraffin, solid paraffin, and microcrystalline paraffin. Owing to its low cost, abundant availability, lack of color and odor, stable physical and chemical properties, and high latent heat of phase change, paraffin is widely applied in fields such as medicine, packaging, construction, military camouflage, industry, and agriculture.

Application scenarios
Packaging:
Paraffin wax enhances the smoothness, strength, and printability of packaging materials while helping lower manufacturing costs. It is therefore widely applied as a paper sizing agent as well as a waterproof and oil-resistant coating.
Industry and Agriculture:
Paraffin wax is extensively used in industries such as rubber, textiles, investment casting, plastics, and electronics. In rubber processing, it functions as an antioxidant, softener, toughening agent, and release agent. In textiles, it serves as a finishing and glossing agent, softener, batik resist material, and water-repellent binder.
Medicine:
Liquid paraffin wax is the most commonly used form in the pharmaceutical sector. It is an oily, viscous organic substance that is insoluble in water and non-saponifiable. With good transparency, easy flow characteristics, and no biological toxicity, it exhibits properties similar to those of biological adhesives.
Construction:
In the construction field, paraffin-based phase change materials are mainly applied in energy-storage gypsum boards, phase change concrete, thermal insulation materials, phase change mortars, and thermal energy–storage floors and ceilings.
Military Camouflage:
Paraffin phase change materials also show significant potential in military applications, particularly in thermal infrared camouflage and infrared decoy technologies.
